5.4.3.3 Replacing the coolant
Drain
– Completely drain the entire cooling system.
– Used coolant must be disposed or recycled in
accordance with laws and local regulations.
Flush
– Flush twice with clean water. Used coolant must
be disposed or recycled in accordance with laws
and local regulations.
– From the Atlas Copco Instruction book, determine
the amount of PARCOOL EG required and pour
into the radiator top tank.
– It should be clearly understood that the risk for
contamination is reduced in case of proper
cleaning.
– In case a certain content of ‘other’ coolant remains
in the system, the coolant with the lowest
properties influences the quality of the ‘mixed’
coolant.
Fill
– To assure proper operation and the release of
trapped air, run the engine until normal engine
operation temperature is reached. Turn off the
engine and allow to cool.
– Recheck coolant level and add if necessary.
5.5 Adjustments and service
procedures
5.5.1 Cleaning coolers
– Keep the water cooler clean to maintain the
cooling efficiency.
– The engine water cooler is accessible via the
service door (1) at the front of the unit.
– Steam cleaning in combination with a cleansing
agent may be applied.
– Close the service door(s).
Remove any dirt from the coolers
with a fibre brush. Never use a wire
brush or metal objects.
To avoid damaging the coolers, angle
between jet and coolers should be
approx. 90°.
Protect the electrical and controlling
equipment, air filters, etc. against
penetration of moisture.
Make sure to not steam clean the
alternator.
Never leave spilled liquids such as
fuel, oil, water and cleansing agents
in or around the generator.
